Make style of listings 9-7 and 9-8 consistent with 9-6

Open frankplow opened this issue 3 years ago • 0 comments

This PR removes superficial differences between listings the reader is asked to compare.

Previously, 9-6 used the style

use std::io::{self, Read};

while 9-7 and 9-8 used

use std::io;
use std::io::Read;

After the PR, all three listings will use the first style.
